Currently, dapps that are deployed to general-purpose blockchain compete with thousands of other applications for space on the network. This can lead to congestion and high fees or even network outages. We’re building software that makes it easy for the most innovative blockchain applications to launch their own ultra-performant blockchains (rollups), enabling applications to own their ecosystem, scale to millions of users, and provide a superior user experience to their users. We already operate chains for a significant user base and are eager to expand that operation with a sleek, performant team.
